Exquisite puzzle game World of Goo is one year old today! To celebrate, developers 2D Boy are encouraging potential players to purchase the PC version for whatever price they deem fit for the next week. Be it a penny or a million pounds, World of Goo is available for any donation you see fit.
For anyone who has yet to try out the game, this is an unmissable opportunity to see what all the fuss is about. Easily in Resolution's top-however-many favourite games of 2008, it's a gorgeously creative indie adventure with fiendish, but always sensible, puzzles.
